When he's not known for releasing really, really terrible solo albums, Chris Cornell is known for being the lead singer of Soundgarden and Audioslave, and the co-lead singer of Temple of the Dog. He revived the latter part of that doctoral thesis quality introduction on Tuesday night when he jumped onstage at a Pearl Jam show in L.A. to sing "Hunger Strike," the most well-known Temple of the Dog single. Cornell actually shows off his pipes, which he's had in storage since 1998, wailing like the dinosaur he used to be before Timbaland and self-absorption got a hold of him. Eddie Vedder wasn't bad either. [Idolator]
